Dairy Allergy, also known as Milk allergy, is an immune response to one or more proteins in cow’s milk or food items that contain cow’s milk. Some proteins in dairy are casein and whey (whey is also known as lactalbumin and lactoglobulin, these are components of whey protein). It is one of the most common allergies among children and most children grow out of this allergy by age 2 or 3. Symptoms usually occur within a few minutes to an hour; however, sometimes it can take a day or two for symptoms to appear.
Eczema (a red, itchy rash), is a skin condition often associated with dairy allergy. If the allergy is outgrown, eczema may replace the allergy symptoms during and after adolescence.
A dairy allergy is not the same as lactose intolerance. There is no immune reaction when you have intolerance, therefore the symptoms are different and require other methods of treatment. Lactose intolerance (can also be referred to as dairy intolerance or milk intolerance) occurs when the body does not make enough of the enzyme lactase. Lactase is the intrinsic enzyme that breaks down lactose, a sugar found in dairy products.
